Oligomeric β-amyloid (Aβ) has recently been linked to synaptic plasticity deficits, which play a major role in progressive cognitive decline in Alzheimer's disease (AD). Here we present evidence that chronic oral administration of carvedilol, a nonselective β-adrenergic receptor blocker, significantly attenuates brain oligomeric β-amyloid content and cognitive deterioration in 2 independent AD ...

A new, simple, sensitive luminescence methods for the determination of carvedilol have been developed and validated. Carvedilol was remarkably quenching the luminescence intensity of the Tb(III) ion in the new terbium complex with 1-butyl-4-hydroxy-2-oxo-1,2-dihydroquinoline-3-carboxylic acid-(4-methyl-pyridin-2-yl)-amide (R) in aqueous solutions containing urotropine buffer (pH 7.5) at lambda(...

Controlled porosity osmotic tablet of carvedilol phosphate prepared and evaluated in this study. Carvedilol phosphate is very low soluble drug. So it is difficult to formulate osmotic tablet of carvedilol phosphate which gives drug release up to 24 hr at zero order. To get desired dissolution profile various formulation parameters like osmogen concentration, level of weight gain and level of po...

A number of elective coronary artery bypass graft (CABG) surgery patients have impaired underlying left ventricular function (poor ejection fraction). This study was performed to compare the effect of postoperative oral carvedilol versus metoprolol on left ventricular ejection fraction (LVEF) after CABG compared with metoprolol. In a double-blind clinical trial, 60 patients with coronary artery...

A high throughput encapsulation technique termed as electrospraying assisted by pressurized gas technology (EAPG) was used to produce nano-within-micro structures of a Biopharmaceutics Classification System (BCS) Class II model drug. Carvedilol is lipid soluble compound, poorly absorbed in the gastrointestinal tract. The produced formulations were characterized terms morphology, crystallinity, ...

BACKGROUND Although carvedilol attenuates left ventricular (LV) remodeling in coronary occlusion-reperfusion, it is not known whether it attenuates ischemic LV remodeling because of coronary stenosis (CS) or permanent coronary occlusion (CO). METHODS AND RESULTS We administered a vehicle, carvedilol, propranolol (2, 10, and 30 mg/kg per day, each), metoprolol (6, 30, and 90 mg/kg per day), or...

BACKGROUND With beta-blocker use becoming more prevalent in treating chronic heart failure (CHF), the choice of drugs raises important theoretical and practical questions. Although the second-generation compound metoprolol is beta1-selective, the third-generation compound carvedilol is beta-nonselective, with ancillary pharmacological properties including alpha-blockade and antioxidant effects....

AIM Studies of beta blockade in patients with type 2 diabetes have shown inferiority of metoprolol treatment compared to carvedilol on indices of insulin resistance. The aim of this study was to examine the effect of metoprolol versus carvedilol on endothelial function and insulin-stimulated endothelial function in patients with type 2 diabetes. METHOD 24 patients with type 2 diabetes were ra...

3-nitropropionic acid (3-NP)-induced neurotoxicity causes a cellular energy deficit and oxidative stress via an irreversible inhibition of the mitochondrial enzyme succinate dehydrogenase (SDH). Systemic administration of 3-NP causes motor and cognitive deficits, particularly those associated with excessive free radical generation. Recently, carvedilol has been implicated as a neuroprotectant i...

BACKGROUND To analyze differences in brain natriuretic peptide (BNP) levels depending on mitral flow pattern (MFP) and to assess the effects of carvedilol on changes in MFP, left ventricular function and exercise capacity. METHODS AND RESULTS The study population consisted of 73 patients with symptomatic heart failure in NYHA classes II and III and LVEF < 40% without prior beta-blockade. In a...
